Keto blueberry crumble recipe FAQs

To ensure you make this recipe successfully, here are answers to many of the commonly asked questions about this crumble recipe:

Are there any ingredient substitution options?

Yes! The below substitution suggestions are options that will work here:

• Classic Monk Fruit Sweetener: Golden Monk Fruit Sweetener will work perfectly and can be subbed in for Classic Monk Fruit Sweetener at a 1:1 ratio. Additionally, erythritol, Swerve, or Truvia can be used in place of monk fruit sweetener at a 1:1 ratio. If you are wanting to use powdered stevia, be sure to check the brand’s website for measurement conversions (stevia is not a 1:1 substitution for monk fruit sweetener).
• Ground Flax Seeds: If you only have whole flax seeds on-hand, simply pulse them in a high-speed blender or food processor until ground. If you don’t have ground or whole flax seeds on-hand, you could try and get away with using chia seeds here, but note that the resulting dish will be quite different than originally written.
• Cream Of Tartar: I use cream of tartar often in place of baking powder, which is often not paleo-friendly. Cream of tartar can be found in the spice aisle of your grocery store, typically right in with the other spices. If you do not have cream of tartar on-hand, baking powder can be used; I would use 1 1/2 tsp of baking powder in place of cream of tartar. Be sure to still use baking soda.
• Melted Coconut Oil: Melted butter can be used in place of melted coconut oil at a 1:1 ratio. Note that this substitution will no longer yield a recipe that is dairy-free, paleo-compliant, or vegan.
• Blueberries: Any low-carb berry should work just fine here, like raspberries or blackberries. Note, however, that this substitution may alter the final nutritional values of the recipe.

Where do I find monk fruit sweetener for sale?

Monk fruit sweetener has become widely available for purchase at most grocery stores, especially specialty food stores and Costco. I personally purchase mine online from Lakanto and have it directly shipped to me.

How is this recipe considered nut-free if it uses coconut flour as an ingredient?

Many people do not know that coconuts are not nuts, but are actually a type of fruit (a drupe). Real Balanced recipes are nut-free and DO contain coconut products.

Here’s what the American Academy of Allergy, Asthma, and Immunology has to say about those with nut allergies consuming coconut:

“Although the Food and Drug Administration labels coconut as a tree nut, the vast majority of tree nut-allergic individuals also tolerate coconut without difficulty, since coconut is not truly a nut, but rather a fruit.”

American Academy of Allergy, Asthma, and Immunology

Please check with your doctor and/or allergist if you have any questions or concerns about consuming coconut.

If you do not eat coconut, check out these coconut-free keto recipes.

Can I substitute in almond flour for coconut flour here?

No. Like most recipes, almond flour and coconut flour are not good substitutes for one another as they have very different absorbency rates. Coconut flour needs to be used here.

Why is a water bath necessary?

You will notice that in Step #3 of the Instructions, a water bath is required. The reason for this is to ensure the crumble cooks evenly within the individual ramekins to avoid any areas of the dish being undercooked or overcooked.

Where do I find ramekins?

I purchased the ramekins I used in this recipe online from Amazon. They are the 4 oz size.

Can I bake this in a pan instead of ramekins?

Yes! Instead of filling individual ramekins, you can fill a 8×8 baking dish with the mixture. Note that the cook time will likely be different than the original recipe states (40 minutes), so just be sure to keep a close eye on it and remove the crumble from the oven when the edges have turned a nice golden brown color.

How many net carbs per serving?

Per serving, these crumbles contain 4.5 grams of net carbs. The recipe will yield 8 servings and one serving is equal to one 4 oz ramekin.

How to store this keto blueberry crumble?

• Refrigerator Storage: Store ramekins in a large airtight container or store them individually by wrapping each ramekin tightly in foil and refrigerating for up to 3 days.
• Freezer Storage: Store ramekins in a large airtight container in the freezer for up to 1 month.

To reheat, bake in the oven at 350 degrees for 10-15 minutes or, alternatively, microwave until the crumble is warmed throughout, about 30-45 seconds.

What to serve alongside breakfast crumble?

If you want to make this crumble for breakfast or brunch, I would suggest serving it alongside these other keto breakfast dishes:

• Cream Puff Chaffles
• Low-Carb Sheet Pan Breakfast Hash
• Sausage Breakfast Casserole
• Keto Savory Jalapeño Cheddar Bacon Scones

How to make this keto blueberry crumble recipe

In a large mixing bowl, whisk together dry ingredients.

Add melted coconut oil and vanilla extract and, using an electric mixer, mix until fully incorporated.

Fold in blueberries.

Spoon mixture into 8 individual ramekins, flattening mixture into even layer using fingers or back of spoon.

Place ramekins atop a baking sheet. Pour 1-inch of water into baking sheet to create a water bath for the ramekins to cook in.

Transfer baking sheet to oven and bake until edges of crumble are golden brown, about 40 minutes.
